Wow. Thanks for your response. Kernel-janitors is sort of a newbie list, and people email me often ask for something to look at. As I mentioned in my email, I was pretty sure the code worked. But I thought it would make a good code reading exercise for someone. But you _nailed_ it. You nailed it to a basketball and then slam dunked it! Btw, I'm sorry if someone forwarded this to you as a support request. I didn't mean to bother the maintainers with this. regards, dan carpeneter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
